PAPER-FEED arra'cmmnr FOR TYPE-WRITERS.

Be it known that .l', BENJAMIN F. I-IU'roHEs, J13,- a citizen, of the United States, residing at Ridgewood, Bergen county, State of New Jersey, have invel'ited'new" and useful 1m- )rovements in Paper-Feed Attachments for ype-l-Vriters, of which the following is a specification.

- This inventlon relates to an atta'clunentf for type-writers, by which a blank sheet is conveyed from a magazine to the type-Writer plat-en, while the previously written sheet is simultaneously removed. thus removed are stacked, preferably, in the same magazine from which the blank sheets are being witlulrawn, so that compactness is insured, all handling of the sheets is avoided,

' and time is. economized.

The invention further comprises automaticmeans for arresting the paper feed in automatically operated type-writers as soon as the sheet has assumed a position for writing the head-line thereon, so that such head-line will be properly spaced from the top of the sheet.

In the accomparrving drawings: Figure 1 is a front elevation of my improved paper feed attachment, showing it coupled to a type-writer platen Fig. 2 an end view thereof, on a larger scale; Fig. 3 an enlarged sec tion 011 line 33, Fig. 1 Fig.- 4 a similar sec tion with some of the parts omitted, and showing the circuit closer in a difierent position; Fig; 5 a detail of the circuit closer; Fig. 6 a detail of the paper support; Fig. 7 an enlarged section on line 77, Fig. 6; Fig. 8 a diagram illustrating the circuit, and Fig. 9 a detail of the sheet separator.

- The paper magazine consists of a box 10 having a cover 11 and adapted to be so connected to a type-writer that its bottom 12 assumes an inclined position with relation thereto.

so that the frame is detachably pivoted to the carriage, while a friction roller 19, journaled in said frame, rests upon platen 15; roller 19 and platen 15 being of substantially the same length. By the means described,

The written sheets To the lower end of box lO'is secured a frame 13 consisting of a pair of side pieces which maybe connected by a longi- .the bottom 12 of magazine 10.

the magazine is free to adjust itself on the pivot 17, until its roller 19 finds a bearing on platen 1 5,'so that in this way the magazine will automatically adjust itself, by its own weight, to assume a roper operative posi tion with relation to t e t -wr1ter.

In order to ment,- one of t e hooks 16 may cooperate with 'a spring-influenced counter-hook 20.

It is obvious that the above means for coupling the magazine to the type writer may be varied and adapted to the special style of pe-writer used.

At its ower end magazine 10 is provided with a support 21 againstwhich the sheets contained within the magazine abut. A

slot 22 between bottom 12 and support 21 permits the egress of the blank sheets, while the ingress of the written sheets takes place over the top of such support. Opposite egress slot 22 there is journaled in frame 13 a feed roller 23 which draws the bottom sheet out of magazine 10 towards platen 15, to which it is held by the usual curved" guards 24 of the type-writer. Feed rolier g 23 is rotated from platen 15 by friction roller 19, which is intergeared with the feed roller by wheels 25, 26, 27. In this way the paper feed is actuated without in any way changing or modifying the construction of the 35 type-writer itself. To bar 14 are secured a number of springs 28, the lower ends of which hold the blank sheet off friction roller 19 and guide it towards platen 15. The

upper bent ends of springs 28 are adapted to 93 press the written sheet against the return roller 29, hereinafter referred to.

In order to set the device to sheets of different thickness, support 21 is adjustabiy secured to frame 13 by set screws 30 that 95 the thickness of the paper. At its lower edge .32, support 21 is preferabiy beveled notched to decrease the friction between such support and the a-per.

The stack of blank s eets 33 is placed upon stack is supported a loose separator 01' partition 34, above which the written sheets 35 pressure upon paper 33 and thus insure an 110 revent accidental displace-i 2 Upon this -1 bent springs 37, form a reslhent guide that directs the written sheets to roller 29. The

. latter is rotated from wheel 27, by wheels 38 and 39, and is so intergeared that it will travel slightly faster than the platen, so as 5 to prevent sagging. Roller 29 delivers the written paper into magazine and stacks 'itu on separator 34.

the attachment is used on type-writers in which the platen isturned automatically,

for the purpose of introducing a new sheet,

means must be provided for automatically i arresting such sheet after the latter has been I laced 1n position for writing the top line.

These means consist of a circuit closer which 5 is adapted to be engaged by the up er edge of blank sheet 33 and arrests the p aten as soon as such engagement-has taken place.

The circuit closer is shown to be of the following construction: In frame 13 is mounted a rod 40 insulated as at 41. At or about the center of this rod there is adjustably secured thereto, by clamp-screw 42, a late or slide 43, to which is pivoted at 44, a ent lever 45. The lower arm of this lever carries a recessed abutment 46 adapted to be engaged by the upper edge of sheet 33. The upper arm of lever 45 carries a set-screw 47 which, .by striking plate 43, controls the lay of the lever. To plate 43 is secured a rame 48 insulated therefrom as at 49 and carrying a contact-screw 50 against which lever may be tilted. To frame 48 is connected a Wire 51 of an electric circuit, the second wire 52 of which is connected to rod 40. t 45 Plate 43 and set-screw 47 are so adjusted with relation to platen 15 and guard 24, that sheet '33, while being fed forward by the platen, will enter with its upper edge the recess 53 formed in abutment 46, (Fig. 3). In this way lever 45 will be tilted from the position shown in Fig. 3, into that shown in Fig. 4, to contact with screw 50, and. thereby close the circuit which arrests the platen. By seittin late 43 at diiierent elevations, 55 the size 0 t 'e'blank heading space oneach sheet may be varied, and isthus under the control of the operator.

The means for arresting'the platen by the closing of the circuit may be of any conco structlon desired, and do not form part of this invention.

As shown in Fi 8, a ratchet wheel 54, is provided with it non-conductin teeth, apair of diametrically 5 opposite teeth eing engaged respectively by ernate conducting and a sliding contact 55 and the awl 56 of -an armature 57. During the fee ing operation, contact 55 and pawl 56 engage conducting teeth of ratchet 54 and thereby close a circuit which energizes an electro-magnet 58. The armature 59 being thus attracted will bring wheel 60 that actuates the platen into engagement with Wheel 61 of power-shaft 62. W en the advancing paper 33 closes the circuit'of wires 51, 52, electro-magnet .63 will 7 be energized to attract armature 57, which, by paw 56, will so turn ratchet wheel 54, that said -pawl and contact 55 will engage non-conducting teeth of the ratchet wheel. In this way the current flowing through 3" electro-magnet 58 will be interrupted to release armature 59 and thereby disengage wheel 60 from wheel 61, so that the platen is arrested and the paper feed stopped. The writing is now performed, and after bein 5 completed, a circuit is closed by the recor that energizes electro-magnet 63 and thereby turns ratchet wheel-54, to again start the paper feed. i

It will be seen that by my invention the sheetsare, by the rotation of the'pl'aten, automatically positioned for. the writing operation and that the written sheets are simultaneously removed, so that a substantial saving in time is effected. Furthermore, the 5 written. sheets may be stacked in the safne magazine that contains the blank sheets, so that simplicity is insured, while a complete separation between the written and unwritten sheets will always take place. Finally, the attachment may be adapted to type-writers of various constructions, and when so ada ted, may be operatively coupled thereto wit out adding anything to the mechanism of the type-Writer itself, or, in any way, changing the construction of such type-writer.
